Abstract

BACKGROUND: Increasing interest in the use of arterial conduits is based on the better patency of left internal thoracic artery (LITA) than that of saphenous vein (SV) graft and radial artery (RA) is emerging as one of them. We compared the early result of coronary artery bypass grafting (CABG) using LITA and RA (RA group) with CABG using LITA and SV only (SV group). MATERIAL AND METHOD: We compared the early operative results of 45 cases in RA group with 45 cases in SV group selected from 165 cases who had CABG between January 2000 and December 2002. The two groups had similar profiles of age, sex, NYHA functional class, left ventricular ejection fraction and coronary angiographic anatomy. We analysed each group on the preoperative risk factors and operative results. RESULT: There were no statically signigicant difference between groups in operative mortality and each morbidities (stroke, IABP insertion, perioperative MI), respectively. However, the overall incidence of mortality and morbidities was lower in RA group compared to SV group (p<0.05). RA group (2.93+/-0.62 days) had shorter duration of ICU stay than SV group (3.55+/-0.95 days) (p<0.001). The patency on postoperative coronary angiography at 7~14 days after operation in RA group patients were 100% of LITA and RA and 94.9% of SV.
CONCLUSION
We had better early operative results in RA group compared with SV group.
